Pegasus 1 or I, known before launch as Pegasus A, was an American satellite which was launched in 1965 to study

Fairchild Hiller, and operated by NASA
.

Spacecraft

Pegasus 1 was a Pegasus satellite, consisting of 1,450 kilograms (3,200 lb) of instruments, attached to the S-IV upper stage of the carrier rocket which had placed it into orbit.[1] It had a total mass of 10,297 kilograms (22,701 lb),[2] and was equipped with two sets of micrometeoroid detection panels, and a radio for tracking and returning data.[1] The panels were 29 meters (95 ft) long, and equipped with 116 individual detectors.[3]

Launch

The launch of Pegasus 1

Pegasus 1 was launched atop a

Cape Kennedy Air Force Station. The launch occurred at 14:37:03 UTC on 16 February 1965.[5] Following launch, Pegasus 1 was given the COSPAR designation 1965-009A, while NORAD assigned it the Satellite Catalog Number 01085.[6]

Pegasus 1 was a secondary payload of

Service Module of a functional spacecraft. Upon reaching orbit, the boilerplate Command and Service modules were jettisoned.[1]

The trajectory and space-fixed velocity were very nearly as planned. The Apollo shroud separated from the Pegasus satellite about 804 seconds after lift-off and deployment of two meteoroid detection panel wings of the Pegasus satellite commenced about 1 minute later.

Operations

Pegasus 1 was operated in a low Earth orbit. On 18 March 1965 it was catalogued as being in an orbit with a

reentered the atmosphere on 17 September 1978.[7] Although minor malfunctions occurred in both the launch vehicle and the satellite, the mission was a success in that all objectives were met.[citation needed
